WORKING WITH LEAD ACID BATTERIES
Use of safety goggles and gloves when working with lead acid batteries is strongly advised.
Avoid contact with the electrolyte as this is acidic and is likely to cause burns to the skin or clothes. If this
occurs you should rinse the affected area with plenty of water immediately. In the event of burns to the skin,
medical advice should be sought if the symptoms persist.
DISPOSAL
In the event that this product must be disposed of, an authorised place for the recycling of electrical and
electronic appliances must be sought. Contact your local authority for information concerning local Household
Recycling Centres with applicable facilities.
This product must not be disposed of with general domestic waste.
RECOMMENDED USES
This product is suitable for charging 12V normal lead acid and AGM batteries of capacities between 20-90Ah
(Ampere hours) only. Check with your device manufacturer if you are unsure about the suitability of this
charger for use with your vehicle, device or battery.
BATTERY CHARGING INSTRUCTIONS
Please read your vehicle manufacturer’s instructions for further information and advice regarding the
disconnection of the battery for charging purposes.
IMPORTANT:
Batteries store large amounts of energy. Avoid short circuits which could result in a dangerous electrical
discharge that could result in personal injury and / or damage to equipment and property.
1. PREPARATION OF THE BATTERY
In the case of sealed lead-acid batteries, firstly remove the caps from each cell and check the level of liquid. If
it is below the recommended level, top up with ionized or distilled water.
UNDER NO CIRCUMSTANCES SHOULD TAP WATER BE USED
To avoid battery acid splashing, the cell caps should be replaced but not tightened until charging is complete.
This allows any gases formed during charging to escape. It is inevitable that some minor escape of acid will
occur during charging. If your battery is permanently sealed it is unnecessary to carry out these checks
2. CONNECTION
To avoid sparks which could cause an explosion, the mains supply should always be disconnected before
making or breaking battery connections. Connect the battery clips to the battery in the following order:
a) Connect the positive charging lead (RED) to the positive post of the battery (marked + / +ve or P).
b) For vehicles with the battery still installed: Connect the negative charging lead (BLACK) to the vehicle
chassis, well away from the battery, fuel line, and hot or moving parts.
For batteries removed from the vehicle: Connect the negative charging lead (BLACK) to the negative post
of the battery (marked - / -ve or N).
After connecting the clips, rotate them slightly so as to remove any dirt or oxidization, thus ensuring a good
contact.
3. OUTPUT SELECTION
WARNING! All selections & connections must be made before the battery charger is switched on.
If you are charging a small battery or you only require a slower rate of charge, set the switch on the front panel
to “MIN”. If you are charging a large or leisure type battery or require a quick boost charge, set the switch to
“BOOST”.

4. CHARGING.
Consider the position of the charger carefully; ensure it is used away from combustible materials.
Insert the battery charger mains plug into the mains supply (230 Volts AC only) and switch the outlet on.
WARNING! DO NOT ATTEMPT TO START THE VEHICLE WITH THE CHARGER CONNECTED. THIS
MAY BLOW THE OUTPUT FUSE OR DAMAGE YOUR BATTERY CHARGER.
Your Battery Charger should now be working and the rate of charge will be shown on the ammeter fitted on the
front of the charger. When a flat battery is initially connected to the Battery Charger the charging rate should
build up quickly. As the battery becomes more charged the rate of charge will drop, this is normal. The
charging current will never fall to zero as the charger will continue to give a small output even when the battery
is fully charged. When charging current has dropped to a low, constant level the battery is fully charged.
A charging time of no more than 10 hours is recommended, at no more than 10% of the battery’s ampere hour
capacity. i.e. 60 Ah battery should be charged at no more than 6Amps for no more than 10 hours. The battery
charger is fitted with an internal, automatic thermal protection device, if the charger overheats due to overload,
environment or for any other reason, charging will be interrupted, charging will restart automatically when the
charger has cooled down. Note: With a fully charged or faulty battery connected to the charger, virtually no
charge may register on the ammeter.
ELECTROLYTE
Regularly check the specific gravity of the liquid, using a hydrometer, until a reading of “Fully Charged” or
1,250 is reached.
5. WHEN CHARGING IS COMPLETE
Switch off the mains supply, unplug the charger and remove the charging clips, negative (-ve / black) first.
Inspect the liquid levels in each cell and top up if applicable / necessary, using the correct fluid. Now push
home or tighten the caps. Any surplus fluid around the cell tops should be wiped off (this should be done with
extreme care as it is acidic). If the battery has been removed for charging, replace it and re-connect the
cables.
FAULTY BATTERY CELLS / GENERAL BATTERY CARE
Batteries are usually made with six cells. One of these cells can deteriorate or get damaged. If after several
hours charging your battery is still flat, you should test the battery. For non-sealed lead acid batteries; using a
hydrometer (which can be purchased from most motor accessory stores), take readings from each cell by
sucking up a small amount of electrolyte to check the specific gravity and condition of the cell. Put the fluid
back into the cell after testing, taking care not to splash the fluid about.
If one reading is lower than the others, this could indicate a faulty cell. The battery will require replacement if
one or more cells are faulty. ALWAYS WASH OUT THE HYDROMETER AFTER USE.
For standard lead acid batteries, but not maintenance free, it is essential to keep the electrolyte level above the
plates. NOTE, however that you should not overfill the battery, as the electrolyte is strongly acidic.
DO NOT USE TAP WATER. Always use distilled or ionised water. If necessary have it checked by your
garage.
It is also important to maintain the battery leads on a regular basis as loose or dirty connections on your battery
terminals may prevent the vehicle from starting. Do this by removing the leads from the battery, cleaning the
inside of each connector and the terminal posts on the battery. Smear the terminal posts with grease, replace
the connectors and tighten firmly.
